Many programming languages, including Java [3] and C#, [4] have built-in support for retrieving the current stack trace via system calls. Before std::stacktrace was added in standard library as a container for std::stacktrace_entry , pre- C++23 has no built-in support for doing this, but C++ users can retrieve stack traces with (for example ...

A delimiter is a sequence of one or more characters for specifying the boundary between separate, independent regions in plain text, mathematical expressions or other data streams.
If-then-else flow diagram A nested if–then–else flow diagram. In computer science, conditionals (that is, conditional statements, conditional expressions and conditional constructs) are programming language constructs that perform different computations or actions or return different values depending on the value of a Boolean expression, called a condition.
